vanvnl Specication of Letters Patent.

Patented oct. '1, 1907.

Application filed February 9V, 1907. Serial No. 356,505.

To all whom it may concern:

Be it known that I, CHARLES F. OBRECHT, a citizen,

of the United States',` residing at Baltimore city and State oiMaryland, have invented certain new and use-v ful Improvements inValves, of which the following is a specification.

My invention relates to an improvement in globe valves and the like, theobject being to provide a valve whereby the life as to the use thereofmay be prolonged and at the same time I have provided a valve with anadjustable and reversible as well as a removable seat, it may thereforebe adjusted at the seat to meet Whatever requirements are necessary toinsure a closure against various pressures; and again II haveconstructed this valve so that when it becomes worn out and rendereduseless, by reason of the seat having worn out that a new seat can bereplaced therein without dispensing with the entire valve, thusrendering a saving to the user, as the scat can be replaced at acomparatively small cost `as compared with an entire new valve, and itis a Well known fact that the seat of a valve is the part which usuallywears out first. By the use oi my device the life considerable extent,prolonged. l

My invention further `consists in certain new and novel features ofconstruction and combinations of parts `which will be hereinafterdescribed and pointed out in of the bolts 4 and nuts 5, secured on thebonnet by simif lar means, viz: bolts A6 and nuts 7 to a gland 8'; 9 isa spindle threaded at 10; 11 is a wheel secured on the lipper end of thespindle 9; 12 is the valve disk; 13 is the collar; 14-14 are valve seatson the collar and l5 are lugs on the collar for the purpose oifacilitating the removal and adjustment of the said collar and theseating of the valve seat; the collar 13 is inwardly threaded aty 16 forthe purpose of being engaged by the threaded body portion 17; thethreads 10 on the spindle 9 are cut contrary to those of 17 on which thecollar 13 screws or vice versa that the 'collar 13 may not have atendency to become unser/.awed by the valve disk being tightly screweddown upon it, for this reason the threads on one should be directlyopposite oi those en the other.

It will be noted that I have provided a seat 14 on the top and alsooneon the-bottom of the collar so that when one seat becomes worn thecollar may be reversed there-l by supplying a new seat. v

Slight changes might be resorted to n the form and arrangement'df theseveral parts described withoutdeparting from'the spirit and scope of myinvention, hence I/,do not desire to limit myself to the exactconstruction as herein set forth; but, l

Having described my invention what I claim as new and desire to secureby Letters Patent, is:

i 1. The combination in a valve of the character described, comprising abody portion provided with an inlet and outlet therein, of a bonnetsecured on the body portion, a gland secured within the bonnet, aspindle provided with a wheel on the upper end thereof, the said spindlebeing extended "through the bonnet and the said gland secured thereinto,the lower end portion of the said spindle being screw threaded andprovided with a valve disk secured on the end thereof, an interiorlythreaded collar, lugs exteriorly provided on the said collar, valveseats formed on the upper and lower edges of the said collar, aninternal threaded body portion upon which the said collar is ses cured,the threads on the said internal body portion being oppositely disposedfrom those on the end of the spindle upon which the valve disk issecured, substantiallyras described.

2. The combination in a valve of the character described, comprising abody portion and a collar, of a valve seat formed on the upper andlowei` edges of the said collar,

lugs exteriorly provided on the collars.V screw threads lnwardlyprovided within the said collar, 'an internal threaded body portion uponwhich the said collar is secured, 'a screw threaded spindle providedwith a valve disk on the lower end thereof, the threads on the spindlebeing oppoVv sitely disposed from those on the said internal bodyportion and within the said collar, substantially as described.

3. The combination in a valve of the character described, and a collar,of valve seats provided on the upper and lower edges of the said collar,screw threads inwardly pro# vided Within the said collar, a threadedvalve stem, a valve disk seured on the lower end of the said valve stem,the said threads on the valve stem being oppositely disposed from thosewithin thesald collar, lugs exteriorly provided on the said collar fo-ythe purpose of adjustment and reA moval, substantially` as described. i

Iii testimony whereof I aihx my signature ln presence of two witnesses.
